YcaO-catalyzed enzymatic reactions and spy BGC. Credit: Nature Chemical Biology (2024). DOI: 10.1038/s41589-024-01736-9 Thanks to a serendipitous discovery and a lot of painstaking work, scientists can now build biohybrid molecules that combine the homing powers of DNA with the broad functional repertoire of proteins—without having to synthesize them one by one, researchers report in a … Read more
Sketch of the pulsed ion source, not to scale. A UV laser pulse enters the UEBIS and is focused onto a LaB6 cathode to trigger ultrafast electron emission. Credit: Physical Review Research. (2024) https://journals.aps.org/prresearch/abstract/10.1103/PhysRevResearch.6.L032066 TU Wien (Vienna) has succeeded in generating laser-synchronized ion pulses with a duration of well under 500 picoseconds, which can be … Read more
Map of how much heavy oxygen there is in local groundwater. Credit: Bowen Lab More than 80,000 American service members remain missing from previous wars, most from World War II. When remains are found, decomposition often makes identification difficult—but not impossible. Even without a name, fingerprints or facial features, our history leaves indelible marks on … Read more

Eagles look on from the trees overhead as the river thunders around boulders nearby. The worker’s back is turned to a … Read more
Credit: Kindel Media from Pexels The deadly H5N1 avian influenza virus, which has killed millions of birds worldwide since 2021—and in rare cases can be transmitted to humans—may be spread through the food-stealing behavior of some seabirds. A study published in the journal Conservation Letters highlights food theft—also known as “kleptoparasitism,” where some seabird species … Read more
Global shark populations are plummeting despite efforts to curb mass killings for their fins. Peruvian authorities said Monday they had seized about 1.3 US tons of illegally harvested shark fins, a delicacy in some Asian countries that has placed the predatory creatures at grave risk. The discovery was made at the warehouse of an export … Read more
Road development in the Congo Basin forest during the last five years. Credit: Remote Sensing of Environment (2024). DOI: 10.1016/j.rse.2024.114380 The Congo Basin rainforest is the second-largest tropical forest in the world, storing large volumes of carbon and hosting high levels of biodiversity. While these forests have historically stayed mostly intact, road development has recently … Read more
The cave-dwelling mysid shrimp Hemimysis margalefi. Credit: Marie Derrien Homing is an animal’s ability to navigate towards an original location, such as a breeding spot or foraging territory. Salmon and racing pigeons are famous for homing, but similar behaviors occur in groups as diverse as bees, frogs, rats, and sea turtles. There, homing individuals are … Read more
Credit: CC0 Public Domain People’s deep connection with the ocean—their “marine identity”—can help us reset society’s relationship with the seas, new research led by Dr. Pamela Buchan, from the University of Exeter, suggests. A diverse, international group of marine researchers and practitioners met to discuss marine identity—based on testimony and photos from multiple countries. The … Read more
